Specification of Letters Patent.

Patented Sept. 14%, 19.15..

Application filed February 19, 1913, Serial No. 749,344. Renewed March 4, 1915. Serial No. 12,109.

To all whom it may concern Be it known that I, RAFAEL IGNAom PAR- rnm, a citizen of the Republic of Mexico, and a resident of Torreon, Coahuila, Mexico, have invented a new and Improved riutomatic Railway-Switch Device, of which the following is a full, clear, and exact description.

My invention has for its objects to provide improvements in automatic railway switch devices, such as shown in my Letters Patent, issued on December 13, 1910, under Number 978,639. In my improvements 1 provide arms, at the side of the track, which are operated by means of the weight of a car on track bars, these arms being secured to rock shafts, to which additional arms are secured, for raising above the ground trip members into position to be engaged by members carried by a car, these trip members having slots in which flattened portions of rock shafts are disposed. The rock shafts are connected by gearing with means for moving a switch point.

Anotherobject of the invention is to provide a member for moving in a guideway on a car, the member having a pivoted arm for engaging the trip member when moved with the car in one direction, the arm being free to move in the said direction relatively to the member and the car, when the car is moved in the opposite direction.

Still other objects of the invention will appear in the following complete specification, in which the preferred form of the invention is disclosed.

In the drawings similar characters of reference indicate corresponding parts in all the views, in which Figure 1 is a sectional view on the line 11 of Fig. 2; Fig. 2 is a sectional view ,on the line 22 of Fig. 1; Fig. 3, is asectional view on the line 33 of Fig. 1; Fig. -1 is an enlarged fragmentary view showing how the track member is adapted to raise the trip member; Fig. 5 is a sectional plan view of Fig. 1; Fig. 6 is a sectional view on the line 66 of Fig. 7, showing the slide through which the trip member is adapted to move; Fig. 7 is a sectional view on the line 7-7 of Fig. 6; and Fig. 8 is an enlarged front elevation showing one of the trip operating members.

By referring to the drawings it will be seen that tracks 5 are provided, and that the switch point 6, which is pivoted at 7, is adapted to move relatively to these tracks 5, in the customary manner, the following means being provided for so moving the switch point 6.

Journaled in a frame 8, disposed below the horizontal plane at the top 9 of the street or road, there are rock shafts 10, which have beveled gears 11, at their inner ends, which mesh with a beveled gear 12 on the plate 13, which is adapted to rotate on its central pivot 14, disposed at 15 in the frame 8. Two of these shafts 10 are provided, one beingdisposed at each side as shown in Fig. 3 of the drawings, and each of the shafts having a beveled gear 11, meshing with the bevel gear 12, on the rotatable plate 13. As a means for rotating these rock shafts 10, I provide trip members 16 one for each of the rock shafts 10, as will be seen by referring to the drawings. These trip members 16 have slots 17, in which are disposed the flattened portions 18 of the rock shafts 10. It'will therefore be seen that when one of the rock shafts 10 is disposed as shown in Fig, 7 of the drawings, with the slots 17 of the trip members 16 in vertical position, the trip members 16 may be raised through the opening 19 in theslide 20, wliich'is provided for covering the opening 21 in the top 22 of the frame 8.

The trip members 16 are raised by means of the curved terminals 23 of the arms 24, these arms 24 being secured to the rock shafts 25. The rock shafts 25, are journaled in bearings in the standards 26, and also in bearings in the sides 27 of the frame 9.

To the shafts 25 are secured additional'ar-ms 28, which are disposed under the ends 29 of the track members 30, so that when the car wheels 31 press down on these track members 30 against the resiliency of the springs 32, the shoulders 33 on the track members 3.0 will engage and depress; the arms 28 to rock the shafts 25, and raise the arms 24, which will, as has been stated, raise the trip members 16.

When the trip members 16 have been raised as has been stated, they are in aposition to be engaged by the operating members 34:, pivoted at 35, to the brackets 36, secured to the member 37, which slides in guideways .38, at the front and rear of the car. As will best be seen by referring to Fig. 8 of the drawings, the trip operating hold the trip members at an angle to each other, and so that the trip members will normally be disposed relatively to each other in the position shown in Fig. 4 ,of the drawings. It will be understood that with the arrangement of the beveled gears 11 and 12, when one of the trip members 16 is moved downward, rotating the rock shaft by means ofthe foot g the rotation of this shaft 1O, the plate 13 10, on which it is mounted, the other trip member 16. will be moved to a vertical position. I

To the rotatable plate 13, there is secured a lug 39, which is engaged by the arms 40 on the lever 41, this lever 41 being connected by a link 42 with a second lever 43, the second lever 43 having an arm 44, disposed between the contact members 45, secured to the shanks 46, theseshanks 46 passing through orifices in the brackets 47, and being held extending inwardly from the brackets 47 by means of the springs 48. The brackets 47 are secured to the shifting bar 49, which is adapted to move in guide members 50, to throw the switch point 6, to which it is articulated at 51. 7

The members 37 are held yieldingly upward on the car 52, by means of the springs 53, which are disposed to the car platform 52, and also to the members 37 shanks 54 beingalso secured to the members 37 passing to the car platform. so that the shanks 54, with the members 37, may be pressed plates 55, at the top of the shanks 54. When a car 52 ismoved along the track so that the wheels rest on the track memhere 30, the trips 16 will be raised inthe manner' which has been described, so'that one of the members 37 is depressed by means of the foot plate 55. The trip operating member 34, pivoted to the said member 37, will be disposed in position for engaging the trip member 16, which is disposed at the same side of the car, and as the car moves along" the track, the said trip member 16 will be moved to rotate the shaft 10, with which it has a sliding engagement. with will be rotated, and by the means described, the switch point 6 will be moved relatively to the point. At the same time the shaft '10 at the other side of the track will be rotated by means of its beveled gear 11, to raise the trip member 16 at the other side of the track.

Having thus described my invention,

I claim as new and desire to secure by Letters Patent 1. In an automatic railway switch device, a track, a switch point movable relatively to the track, a member mounted to rotate on a vertical axis, means by which the member is adapted to move the switch point, a shaft, gearing connectingthe shaft with a member for rotating the latter, a,
